css: add text +/- markers to the diff to improve readability for colour blind 
(fixes #77)

This seems unrelated to https://bitbucket.org/conservancy/kallithea/issue/77 ?

Do we really want to make the diff look so much more like the normal diff format? I kind of consider it a feature that the changes shows up more cleanly.

A column with +/- needs eye flickering to parse when looking at the actual changes elsewhere on the lines. It might be nice to have for those who are used to the format but we shouldn't rely on it or make colorblind rely on it we can avoid it.

I don't know how good or bad the colors are for the different kinds of color blindness. Is it solving a real problem? I think it would be a better help for color blind if we made sure that the deleted lines were darker (and thus with lower contrast) and the context lines were brighter (and thus with lower contrast) so the actually changed lines stood out most clearly.

Anyway: Do we need to use yet another column of the precious horizontal space for this purpose? Couldn't it reuse the new empty column where the comment bubble might show up?
